A board with a SAM7-chip that is. You&rsquo;ve got the schematic, from my experience it is all correct, what more documentation do you need?</p>Bohica on DEV-00775 - Header Board Atmel SAM7-256Bohicaurn:uuid:9f5e0318-bddc-214a-b1d5-449a34eb2fe02010-03-01T08:06:38-07:00<p>Buyer Beware!!<br/>
The peeps @olimex are flat unresponsive. I wouldn&rsquo;t recommend their stuff at all. Documentation is poor at best. And yes I have sent several emails from private IP addresses to clear their SPAM filter. Ha!<br/>

I hope to use this as a replacement for the AT91SAM7S-EK devboard from Atmel, which is $100.<br/>
The only additions I can see for my $50 are a pair of RS-232 chips and associated connectors, 4 LEDs on I/O ports, a small prototyping area, and a big &ldquo;ATMEL&rdquo; logo. What a deal!<br/>
Anyone have a thought on replacing the 18.432 MHz crystal with something a little faster? The ARM is good up to 60 MHz&hellip;why was this slower crystal chosen?</p>
